Hi,
I have a Worcester Greenstar 30CDi boiler long with a separate hot water tank. I have noticed in recent weeks that the pressure is dropping to zero almost daily after the CH has been running. It doesn't appear to drop when just the HW schedule is on to heat the water tank.
I can see there is an open plastic connector between 2 of the copper pipes that has water dripping when the CH is on. This leads outside to be dumped so it seems this is why its dropping. I do not know why though. I have added a couple of links to a picture as I cannot see any label on the connector to confirm what it is (hopefully the experts will know!)

There is an expansion tank above this pipework which may be playing a part. The whole system is around 10 years old, maintained annually and still appears to be in good condition aside from the pressure issue.
Any advice appreciated so I know if its something I can fix as a competent DIY'er or I need professional help.
Thanks
